药材的害虫种类很多,有些害虫为害相当严重,过去由于长期应用化学农药进行防治,使一些害虫产生抗药性。有些药材还因应用化学农药而降低其有效成分的含量和品质,或存在残毒问题。采用生物防治可以克服化学防治的一些缺点。作者于1973年对一些药材害虫进行了微生物制剂室内防治试验及天敌调查等生物防治研究,取得一些初步结果,现整理如下,以供有关方面进一步研究或生产应用时参考。
Many kinds of medicinal pests, and some pest damage is quite serious, in the past because of long-term use of chemical pesticides to prevent and control, so that some pests produce resistance. Some herbs also reduce the content and quality of their active ingredients due to the use of chemical pesticides, or there is residual problem. The use of biological control can overcome some of the shortcomings of chemical control. The author carried out biological control research on some pesticide pests in indoor prevention and control and natural enemies investigation of some medicinal pests in 1973, and obtained some preliminary results, which are summarized as follows for reference of relevant parties for further research or production application.
